Question

[2 cosec (30°)2 + sec (45°)2 +sec (60 °)]

Answer 1

Step-by-step explanation:

cosec30°=2

sec45° = root2

sec60°=2

2 (cosec30)^2 + sec^2(45°) + sec(60°)

2×4 + 2 + 2 =12

answer 12 dude

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

${\bf{\green{=>[2(1/sin30°)^2+(1/cos45°)^2+(1/cos60°)]}}}$

${\bf{\red{=>[2(1/1/2)^2+(1/sqrt3/2)^2+(1/1/2)]}}}$

${\bf{\blue{=>[2(2)^2+(1/1/sqrt2)^2+2]}}}$

${\bf{\pink{=>[2(4)+2+2]}}}$

${\bf{\green{=>[8+2+2]}}}$

${\bf{\orange{=>[12]}}}$
